- Have a current rating of at least that of the maximum power of your charging station. E.g., 16A or higher for 16A charging station.
- Have normally open (NO) contacts. When voltage is applied to the contactor terminals (usually marked A1 and A2), the contact closes.
- The coil rated voltage (between A1 and A2) should be 230V AC.
